I answered but they hung up.

It's a company that keeps calling me, when I call them back to see what they want an tell then stop calling I just get a machine. They call five to six times a day from 8am to 9pm.

Unknown caller left no message 8pm 8/1/12

I received a call from this number about 5:20 Eastern time.  It's "Microsoft" calling about a problem with my computer.  It's a phising call, if you do what they tell you to do they'll control your computer.  PS it's not really Microsoft.  Microsoft doesn't call you to report a computer problem.

The caller had an Indian or a Pakistani accent.  And didn't speak English well.

Caller claimed to be from IRS and that I was being sued; did I have a lawyer!  I said the IRS would send me things through the mail, not by phone.  He claimed that they tried to send mail .  I hung up on him.
